Store heat without any losses. The energy generated by the heat pump is not always completely used immediately. Then it makes sense to store the heat generated with renewable energy efficiently and with the lowest possible losses. That makes our heat storage system an important component of every future-oriented heating system. Regardless of whether it is a matter of heating warmth or hygienically perfect domestic water: Heat storage is an important element in a modern heating system.
Buffer storage tanks ensure that the heat source and the heat consumption are decoupled. This means that heat is generated regardless of when it is consumed and your heat pump does not have to start up again every time you turn up a radiator for example.
Hot water storage tanks ensure that there is always enough hot water available, even if everyone wants a bath. Just like the buffer storage, generation and consumption are decoupled here as well.
Combined storage tanks unite buffer storage and hot water storage in one unit. The two types of storage are strictly separated from one another. Combined storage is often the optimal solution if there is little space in the cellar, but you would still like to have an efficient and environmentally-friendly storage system.
x-buffer combi pro – heat pump control, buffer storage tank, and hot water storage. The combined storage tank contains all important components for connecting an x-change dynamic pro heat pump and will impress you with its simple and clear design. All electrical components are already wired up to the integrated control ex works, reducing cabling effort required on site to an absolute minimum. The installed x-center pro heat pump control is impressive with its high resolution capacitive 7" colour touch display with intuitive and simple menu control with self-explanatory icons and innovative overview screens. Functions like Smart Grid , Power to Heat and electronic heat quantity measurement are also integrated, as well the option to incorporate additional Kermi devices via modbus. The x-center pro control can be remotely serviced without the need for further accessories and the heat pump can be operated by remote control web-based over the internet. The space-saving combined solution for heating warmth (127 l buffer storage tank) and hot water (231 l domestic water storage tank) makes the entire installation of the heat pump easier, saves space and time during assembly, and therefore reduces the overall investment costs. All maintenance is done from the front, even the 2 magnesium signal anodes with visual indicator for anode replacement can be changed quickly and easily from the front.
x-buffer compact combi – buffer storage and hot water storage. The x-buffer combi combines buffer and hot water storage in one, pleasant warmth from your heating and plenty of hot water. It contains all important components for connecting an x-change heat pump and will impress you with its simple and clear design. All the electrical components are completely pre-wired and the innovative and flexible line routing for makes for short line routes in tight spaces. The space-saving combined solution for heating warmth (127 l buffer storage tank) and hot water (231 l domestic water storage tank) makes the entire installation of the heat pump easier, saves space and time during assembly, and therefore reduces the overall investment costs. All maintenance is done from the front, even the 2 magnesium signal anodes with visual indicator for anode replacement can be changed quickly and easily from the front.
x-buffer flex – layered buffer storage tank Especially for use with heat pumps. The two temperature levels for hot water and heating, in conjunction with the integrated inflow dampers, ensure optimum temperature stratification and ensure that the heat generated is stored efficiently. Additional connections on both sides allow flexible integration of further heat sources on site. The high quality, 130 mm thick, 2-layer insulation made of 110 mm EPS and 20 mm fleece reduces storage losses to a minimum. Due to the small tilt and door frame dimensions and the optimally matched system components, simple, fast and error-free installation is ensured. The layered buffer storage tank is impressive with its modern design as well as by allowing quick and self-explanatory, flawless installation of the hydro module.

x-buffer compact cool buffer storage. Can be used for heating and cooling modes with heat pumps. The buffer storage tanks store the heat energy generated and deliver it to the heating system. Thanks to modern PU rigid foam insulation, these innovative storage tanks keep heat loss to an absolute minimum. The x-buffer compact cool buffer storage tanks are versatile and have flexible uses, including for use in cooling mode with heat pumps.
x-buffer compact / cascade buffer storage tank. Store the heat energy generated and deliver it to the heating system. Thanks to modern fleece insulation, these innovative storage tanks keep heat loss to an absolute minimum. The buffer storage tanks are versatile and flexible in use and have many connection options. The x-buffer cascade has been designed especially for the application of heat pump cascades and has 2" nozzles for connecting the heat pumps heat pumps to the heating system.
x-buffer fresh domestic hot water storage. High-performance storage tank for domestic water heating in conjunction with a heat pump. With its high quality PU-thermal insulation, the x-buffer fresh is in energy efficiency class B. The x-buffer fresh is available in two sizes.

The special layering process guarantees optimal layering of layers of water at different temperatures in the Kermi x-buffer layered buffer storage tank.
Mixing volumes of cold and warm water is virtually impossible with this process which has a patent pending. The water which slowly flows into the storage tank can rise or sink, depending on the temperature. Together with high quality all-round insulation, this significantly minimises energy losses.
The innovative housing design of the x-buffer layered buffer storage tank makes the storage unit a space-saving alternative.
The system does not take up any more room than a conventional heating tank. Thanks to a special floor construction, the tilt dimension (diagonal) is scarcely any greater that the setup dimensions. This means that from the outside as well, the x-buffer layered buffer storage is also different from conventional storage models and is highly suitable for rooms with low ceilings in existing buildings. With the intelligent arrangement of the connections, the x-buffer also fits through narrow doors.
Finally the new Kermi heating system has been installed. Or the Kermi ventilation system. Nothing left to stop you feeling cosy at home. With our 5-year system warranty, we are happy to prove the quality of our products and our service promise to you.
1. Have the Kermi system installed by a specialist company
2. Have Kermi Customer Service commission the system (or in the case of ventilation systems, a specialist company)
3. Annual servicing by Kermi Customer Service or by a specialist company
The topic of thermal comfort is really quite complicated and some of the terms used often need explaining. That is precisely when I can help you! As a real specialist, I am very familiar with all the system components and the way they work together, so I am able to explain these situations very clearly and in a way that is easy to understand.
